Title: Modular motorized electric wheel hub assembly for bicycles and the like
Inventor: BIRKESTRAND ORVILLE J
IPC: B60L11/18
Filed: 1999-04-21
Abstract: A motorized wheel hub assembly includes a sealed motor section having first (68) and second (92) coaxial shafts (72) extending from the motor section, the second shaft being a rotary shaft and a gear reduction section adjacent to the motor section, the gear reduction section including a pinion (122) at the end of the rotary shaft, a plurality of planet gears (114) rotatably mounted to the housing in meshing engagement with the pinion (122) and a third shaft (72) connected to the motor housing, all of the shafts being separate but coaxial. A hub (26) having an interior surface closely surrounds the motor and gear reduction sections and is rotably coupled to the first and third shafts.  A ring gear (136) formed in the interior surface of the hub is in meshing engagement with the planet gears so that when the second shaft rotates at a selected speed, the hub rotates relative to the first and third shafts at a lesser speed. Preferably, the hub is partially filled with oil to conduct heat from the motor section to the outside.

Patent CA-2334027-A1 (CA)
Inventor: LE-KHAC BI
IPC: B01J27/26
Filed: 1999-06-07
Abstract: The amount of high molecular weight impurity present in a polyether polyol produced by alkoxylation of an active hydrogen-containing initiator using an epoxide such as propylene oxide and a substantially amorphous highly active double metal cyanide complex catalyst may be advantageously lowered by having a non-protic Lewis acid present during the epoxide polymerization. The use of halides such as zinc chloride and aluminum chloride is especially effective for such purposes. In a preferred embodiment, minor amounts of water are also present during polymerization. The higher purity polyether polyols thereby produced are particularly useful in the preparation of slab and molded polyurethane foams, which tend to collapse or become excessively tight when elevated levels of high molecular tail are present in the polyether polyol.

Title: A process for making partially digested soy protein-containing dressing
Inventor: SIMONSON JULIE A
IPC: A23L27/60
Filed: 2001-11-05
Abstract: A process for incorporating soy proteins in emulsions of edible oils is provided. Such emulsions include, but are not limited to, pourable and spoonable salad dressings. The process comprises treating a soy protein isolate with one or more protease enzymes in an enzymatic hydrolysis step to prepare a partial hydrolysis or digest of the soy protein. The hydrolysis step is carried out using an effective amount of protease enzymes selected for their effectiveness in hydrolyzing the soy proteins, and for the flavor profile provided in the final end product using the partially digested protein. The soy protein is hydrolyzed for a time and at a temperature effective to partially digest the soy protein isolate without developing adverse flavor characteristics in the partially digested isolate. Typically, the degree of hydrolysis or proteolysis of the soy protein is about 3 to about 30 percent, and more preferably, about 5 to about 15 percent. The dressings prepared with the partially hydrolyzed or digested soy protein do not exhibit the graininess, poor texture, or soy bean flavor normally associated with soy proteins.

Title: Improvement in the assembly structure of a high door
Inventor: WANG CHEN KUEI-YUNG
IPC: E06B3/70
Filed: 2001-11-07
Abstract: The invention relates to an improvement in the assembly structure of a high door. This improvement is characterized by the inner side of an upper longer region (above the handle) of the left edge-sealing angle bar and the inner side of a lower shorter region (below the handle) of the left edge-sealing angle bar being inlaid with two U-shaped reinforcing irons the length of which corresponds to the length of the two regions. A first wood strip the length of which is slightly shorter than that of the left edge-sealing angle bar is inserted into the U--shape of the two U-shaped reinforcing irons, then joined, by a nail gun and an adhesive, to a second wood strip. The handle position is then inlaid with a reinforcing angle bar. The inner side of the right edge-sealing angle bar is inlaid with a U-shaped reinforcing iron the length of which is slightly shorter than that of the right edge-sealing angle bar. A third wood strip with a length corresponding to that of the U-shaped reinforcing iron is inserted therein and joined, by a nail gun and adhesive, to a fourth wood strip. The structure is coated with an adhesive and press-assembled with two contoured door skins. After assembly, a hole is drilled in the bottom edge-sealing angle bar and the hollow core formed by the two contoured door skins is filled up with ammonium polyester foamed plastic to form a high door structure which will not bend or deform.

Title: Method for production of three-dimensionally arranged conducting and connecting structures for volumetric and energy flows
Inventor: GOTZEN REINER
IPC: B29C67/00
Filed: 2000-12-08
Abstract: The invention relates to a method for production of three-dimensionally arranged conducting and connecting struc-tures for volumetric and energy flows. Various light-setting materials are used for the production of the layers. Upon exchanging the materials, those layer regions in which no setting occurred during the preceding setting process, are also filled with new material, such that, in the subsequent setting process, not only is the upper layer linked to the one lying directly beneath it, but also material of the upper layer is connected to the material of a layer lying below the penultimate layer. It is thus possible, within the layer sequence, to connect a structure with varying properties from layer to layer.

Title: Method of making a capillary channel
Inventor: BRENNEMAN ALLEN J
IPC: B01L99/00
Filed: 2001-11-27
Abstract: An optical reagent format with a precise capillary chan-nel is made by molding a format on a carrier of a precise pre-determined thickness. The carrier includes an insert at least a portion of which is molded in the format. Once the format is made, the insert is detached from the carrier and removed from the format leaving a precisely dimensioned capillary channel with an inlet and vent. A reagent may be applied in the capillary channel and the format used to measure the ana-lyte in a fluid such as blood.      An electrochemical sensor with a capillary channel is formed by placing a sacrificial insert and electrodes on a sensor base and applying plastic material. After the plastic material is cured, the sacrificial is removed leaving a capil-lary channel in the sensor. The inserts may be removed by a tool including a clamp for clamping and holding each insert stationary and a sliding block to which the sensor is secured.

Title: A method and apparatus for determining the resistivity of a formation through which a cased well passes
Inventor: EHRET PATRICK
IPC: G01V3/20

Abstract: The invention relates to a method of surveying a geological formation through which a cased borehole passes, said method being characterized by the fact that: in a first step, current is injected into the casing at a first point spaced apart longitudinally from said formation so as to cause current to leak into said formation, and electrodes defining two consecutive sections of casing situated at the level of said formation are used to measure the respective potential drops along said sections; in a second step, current is injected into the casing at a second point spaced apart longitudinally from the formation and situated on the opposite side thereof from said first point, so as to cause current to leak into the formation, and said electrodes are used to measure the potential drops along said sections;  the corresponding measurements of the two steps are combined to obtain the values corresponding to a circuit formed by the casing between the two injection points and essentially exempt from leakage into the formation; and the current leakage that is indicative of the resistivity of the formation is determined on the basis of the measurements taken in the first step and in the second step, and of the values resulting from said combination.
